全复合材料主承力梁结构研制与分析验证

根据结构特点和受力特性,研制了一种全复合材料主承力梁结构。给出了主梁的铺层设计,详述了其成形工艺。基于MSC.Patran/Nastran建立了主梁有限元分析模型,采用线性求解器对多级载荷作用下的主梁进行了静强度分析,给出了结构应变与位移结果。同时设计了强度试验方案,对主梁结构进行了静强度试验验证,采集了应变与位移信息,确定了结构的响应。结果表明,全复合材料主承力梁结构满足强度设计要求,为复合材料应用于主承力结构提供了依据。

Manufacture and Verify of Composite Main Loading-Bearing Beam

According to the structural characteristics and mechanical characteristics, we developed a compositemain loadin-bearing beam structure. This paper presents the design of the main beam overlay detailing its formingprocess. Based MSC. Patran/ Nastran establish a main beam finite element analysis model using linear solver main un-der multi-level load beam static strength analysis, it shows the structure of the strain and displacement results. Whilethe design of the strength test program, the main beam structure static strength test was verified, strain and displace-ment information was collected to determine the response of the structure. The results show that composite main load-ing-bearing beam structure design meets the strength requirements,and provide reliable data for the composite materi-als used in primary load-bearing structure.
